Energy is dissipated as the discharge falls into the plunge pool as a free-flowing jet. Plunge pools are commonly lined with rock riprap or other material to prevent excessive erosion of the pool area. Discharge from the plunge pool should be at the natural streambed elevation. Typical problems may include movement of the riprap, loss of fine..."

Multiple rows of baffle piers on the chute prevent excessive acceleration of the flow and prevent the damage that occurs from a high discharge velocity. A portion of the baffled chute usually extends below the streambed elevation to prevent undermining of the chute. <ref name="ASDSO">[https://damsafety.org/da..."

Type II basins contain chute blocks at the upstream end and a dentated (tooth-like) endsill. Baffle piers are not used in a Type II basin because of the high velocity water entering the basin. Type III energy dissipators can be used if the entering flow velocit..."
- 19:2219:22, 2 December 2022 diff hist +844 N Impact Basins Created page with "__NOTOC__ Category:Energy Dissipation ---- Concrete impact basins are energy dissipating devices located at the outlet of the spillway in which flow from the discharge conduit strikes a vertical hanging baffle. Energy dissipation occurs as the discharge strikes the baffle; thus, performance is not dependent on tailwater elevation. Most impact basins were designed by the NRCS and the USBR. <ref name="ASDSO">[https://damsafety.org/dam-owners/outlet-erosion-control-stru..."

Headwalls/endwalls are typically made of concrete and should be founded on bedrock or have an adequate foundation footing to provide support for stability. A headwall/endwall can experience undermining and become displaced if not adequately designed. Displacement of the headwall/endwall can..." current
